Abstract

The invention is applied to the technical fields of sensing control of industrial robots, and provides a method and device for calibrating sensor postures of a robot in real time and terminal equipment. A binding position of a sensor is arranged on the robot; and the sensor is arranged on the binding position. The method for calibrating sensor postures of the robot comprises the following steps: building a robot motion coordinate system and a sensor coordinate system; controlling orientated motion of the sensor; acquiring six-dimensional posture data; calculating an initial posture relation ofthe sensor coordinate system relative to the robot motion coordinate system; calculating posture converted quantity of the binding position relative to the robot; and calculating the posture relationof the sensor relative to the robot according to the posture converted quantity of the binding position relative to the robot and the initial posture relation of the sensor coordinate system relativeto the robot motion coordinate system. According to the method and device for calibrating sensor postures of the robot in real time disclosed by the invention, the phenomenon that control errors caused by the change of the sensor postures during control of the positions and the postures of the robot is avoided.

Description

Technical field [0001] The invention relates to the technical field of industrial robot sensor control, in particular to a method, a device and terminal equipment for calibrating the attitude of a robot sensor in real time. Background technique [0002] Sensing and measurement are an important part of the control system, and the most widely used multi-dimensional force sensor is the six-dimensional force sensor. The generalized six-dimensional force sensor can check the three-dimensional orthogonal force and three-dimensional orthogonal torque in any force system in space. Due to its rich force measurement information and high measurement accuracy, it is mainly used in force and force-position control situations, such as the end of a robot Actuator, wheel force detection during automobile driving, contour tracking, precision assembly, hand coordination, etc. As a signal input device, the six-dimensional sensor can generate signals describing position and attitude such as transla...
